We changed the LAN PHY from Realtek to Microchip as latter is more reliable supplier for both commercial and industrial temperature components, we searched desperately Realtek PHY in industrial temperature grade but without success.

We extended the input working voltage from 6-16VDC to 8-24VDC

We changed the NAND Flash to eMMC (but old NAND style flash is still possible to assembly)

The Ethernet PHY change requires new patches on the Uboot and Linux images which are already uploaded.

A20-OLinuXino-LIME2-eMMC was developed first for customer of ours, but after we saw the result we decided that it’s good to add it in our web shop.

What difference make eMMC instead of NAND Flash?

eMMC behaves like SD-card so no need for special drivers, you write on it as you write on SD-CARD, it’s faster than NAND Flash, and it’s more reliable.

The eMMC Flash we use is industrial grade -40+90C SLC Flash from Micron. All other functionality remains same. Note thatA20-OLinuXino-LIME2-eMMC is still not 100% industrial temperature grade, the DDR3 and Ethernet PHY are in commercial temperature grade (0-90C for the DDR3 and 0-70C for Ethernet PHY), we have industrial grade DDR3 and can build A20-OLinuXino-LIME2-eMMC with such memories,so the next step to complete industrial grade temperature board is to find proper industrial grade Ethernet PHY chip.

The LCD 7″ Metal Frame Box is now in stock. We offer it only in black color.

Inside the frame there is space to assembly A10 or A20 OLinuXino LIME or LIME2:

All connectors of LIME are exposed on two sides on the frame box:

and from other side:

Four M4x8 screws hold together the two parts of the LCD frame, the same can be used to attach the frame to any flat surface.

The LCD assembly is easy to do but involves making frame of dual adhesive tape around the LCD to keep the glass off contact with the metal and to attach the touchscreen if necessary.

We offer this assembly as separate service if one do not want to make it himself. Here is the link for the assembly service – it’s orderable item in the web shop.

Please note that before you add LCD7-ASSEMBLY to your order you also have ordered these items: A10 or A20 OLinuXino LIME or LIME2, LCD-OLinuXino-7 or LCD-OLinuXino-7TS, LCD7-METAL-FRAME and CABLE-40-40-10CM otherwise we can’t do the assembly 🙂

The next logical step is to make Industrial panel. For this purpose we need LIME or LIME2 in industrial temperature grade.

A10/A20 qualify for industrial temperature grade, we also have all other components in this temperature range including the DDR3 memory, but two components preventing us to complete this job: NAND Flash and Ethernet PHY.

We work to solve this and in couple of months we may have in our web shop complete industrial panel solution with LCD, LIME etc in Industrial temperature grade -45+85C .

What you see is our first sample of the metal frame for 7″ LCD with build-in A20-OLinuXino-LIME inside!

Our mechanical designer is getting better and better after the design of A20-OLinuXino-MICRO and A20-OLinuXino-LIME boxes. The box for MICRO was done after three attempts, the LIME box was done right from the second attempt, now the LCD box got perfect from the very first attempt!

The metal frame is done by three parts:

Here above you see two parts, which connect together with single screw. Why this is necessary – LIME has connectors on both ends and it’s not possible to fit inside as the connectors go outside PCB borders

this is the third part it’s bend to hold inside the touch panel and LCD:

here is the frame with LCD and touchscreen in it:

the LIME is attached to back panel with one screw on metal spacer, the left side connectors show outside a bit:

then we attach the right side panel and screw them together:

then the LCD part is snap to the other two and fixed with 4 screws:

here is how it looks on the back side:

the same four mount holes can be used the metal panel to be assembled to other surface there are provisional mount holes on the back side as well.

The whole construction is solid and reliable. The frame dimensions are: 190 x 102 mm the higher back side is 40 mm the lower side is 10 mm thick.

This whole frame have approx same size as MODEL-B box and have just few more bendings so the price I expect is to be same as on MODEL-B box i.e. about EUR 15.00

This means 7″ LCD panel with A20-OLinuXino with the metal frame will cost from EUR 81.00 and if TOUCH screen is add from EUR 89.00
